Application filed March 1,1899. Serial No. 707,309. (No model.)

T0 @ZZ wwm, it may concern:

Be it known that we, CHARLES H. BEEVER, of Pearsall, in the county of Frio, and VIL- LIAMA. l\ICCOY,of Campbellton, in the county of Atascosa, State of Texas, citizens of the United States, have invented a new and useful Cactus-Burner, of which the following isV a specication.

Our invention relates to a cactus-burner consisting in an apparatus for removing thorns from cactus or prickly-pears or similar plants or growths of a fleshy or succulent nature provided with spines, the removal of these spines adapting the plants to be fed to stock without incurring the risk to which the stock would be exposed by reason of the natural or normal condition of the plants.

The particular object of the present invention, which consists of an improvement upon the construction shown and described in a patent to Edmunds, No. 613,798, granted November 8, 1898, is to provide au improved construction of burner Yand means for controlling the position thereof in connection with a tank or reservoir of portable construction, of which the contents maybe subjected to the desired pressure.

' Further objects and advantages of this in-v vention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

1n the drawings, Figure l is a perspective view of an apparatus constructed in accordance with our invention. Fig. 2 isasectional view of the burner.` Figs. 2iL and 2b, are respectively longitudinal sections of one of the swivels and the grip of the delivery-tube. Fig. 3 is a detail view of the pump or pressure-applying device. Fig. 4 is a detail section of the feed-valve of the pump mechanism. Fig. 5 is a detail view of a slightlymodified construction of burner wherein the axis of the coils is parallel with the inlet-terminal of the burner.

Similar reference characters indicate corresponding parts in all the figures of the drawings.

The tank or reservoir l-is of portable size and weight and is preferably provided with rings or keepers 2, with which are engaged the extremities of a shoulder-strap 3 to adapt the apparatus to be slung over the shoulder of the operator, said tank also being provided with a filling-opening fitted with a cap 4.

Communicating with the tank at one end is a delivery-pipe 5, consisting of a metallic tube having'one or more swivels 6, by which the proper position of the burner 7 at the extremity of the tube may be attained. ln the construction illustrated this delivery-tube is provided adjacent to its point of communication with the tank with a cut-off valve 8, and beyond this valve and at an intermediate point of the length of the delivery-tube is arranged a transverse portion 5a, forming an elbow, in which one of the said swivels 6 is located to adapt the free end of the tube or the burner to be raised and lowered in the operation of the apparatus. Also adjacent to the elbow we preferably locate another swivel, as indicated, to allowA the burner to be turned about the delivery-pipe as a center.

The burner consists of a single tube of the proper dimensions folded upon itself-to form a helical coil 9, one terminal of which is bent to lie against the exterior of the coil and parallel with the axis thereof and extending throughout the length of the coil, as indicated at l0, and is then connected with the ldelivery-pipe. The Vother terminal of the coil is extended parallel with the axis thereof and is doubled'upon itself to form a burner-tip ll, lying in axial alinement with the coil. This burner-tip is provided with a central orifice l2 and with a plurality, as two or more, lateral obliquely-disposed orifices 13, which are adapted to project vaporized fuel directly upon the adjacent terminal convo- Vlution of the coil to maintain a proper vaporizing temperature thereof. The burner-tip is preferably spacedfrom the adjacent terminal of the coil to insure the proper admixture' ,e estare Applied to the front end of the tank or reservoir, on that end from which extends the delivery-pipe, is a pump mechanism having a barrel or cylinder 14 and a piston 15, of which the stern or rod terminates in a suitable handhold 16 within convenient reach of the operator. This cylinder or barrel is in communication with the interior of the tank by means of an air-conducting tube 17, having a check-valve 1S opening into the tank to lallow air to be forced from the barrel or cylinder of the pump thereinto. To prevent subsequent leakage from the tank into the pump-barrehwe also preferably employ a cutoif valve 19, arranged in operative relation with a seat 20, located near the check-valve seat and adapted to be closed after the desired pressure has been attained in the tank.

In operation the burner,of which the length or axis of the coil is arranged transverse to the delivery-pipe, as shown in Figs. l and 2, is so disposed that the burner-tip discharges downwardly, and by passing the burner over a heap of cactus or prickly-pear plants the flame will be forced downward through the heap and will consume the objectionable spines, the desired position of the burner being possible by reason of the swivels with which the discharge-pipe is provided, and the latter being provided with a grip 2l, by which the operator may readily control the motions of the same. We may, however, arrange the burner with the axis of its coil parallel with the delivery-pipe, as shown in Fig. 4, in which case the llame is discharged in a direction approximately parallel with the, deliverypipe, and the manipulation of the latter will be correspondingly varied.

The grip which we have illustrated preferably consists of a sleeve adjustably fitted upon the delivery-pipe and provided with terminal clamping-nuts 22, by which it may be secured at any desired adjustment to suit the length of arm and convenience of theoperator. By grasping the grip the operator is enabled to elevate or depress the burner end of the delivery-tube and also to turn the latter to direct the llame from the burner as may be desired to accomplish the required result.

It will be understood that in practice various changes in the form, proportion, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacri ficing any of the advantages of the invention.

Having described our invention, what we' axis of the coil and having central and lateral f oritices, substantially as specified. l

2. In an apparatus of the class described, the combination with a tank or reservoir, of a delivery-pipe in communication therewith, a burner comprising a helical coil, the axis of which is arranged transverse to the adjacent portion of the delivery-pipe, one termi nal of the coil being extended at right angles to the axis of the coil to form an inlet-tube, and the other terminal being extended and bent upon itself to form a burner-tip alined with the axis of the coil, and a swivel connection between the burner and the deliverypipe, whereby the burner-tip may be caused to discharge through the coil radially ofthe delivery-pipe and at different degrees of its rotation with respect to the tank.

3. In an apparatus of the class described, the combination with a tank or reservoir, of a delivery-pipe having a transverse elbow portion pivotally swiveled whereby the free end of said pipe is adapted for rotation, a burner having a helical coil one terminal of which is extended t-o form an inlet-tube terminally arranged at right angles to the axis of said coil and connected by a swivel to the' free end of said delivery-pipe, and the other terminal of the coil being extended and bent upon itself to form a burner-tip in alinement.

with the axis of the coil, whereby the burnertip may be caused to discharge through the coil at every angle with respect to the tank.'

In testimony that we claim the foregoing as our own we have hereto affixed our signatu res in the presence of two witnesses.
